Abstract

The reactions of CnSc+ (n=2–6) with O2 have been studied by using an rf ion trap. CnSc+ was produced by the laser ablation of a mixed sample of graphite and scandium. Observed reaction product ions were ScO+ for all CnSc+, and ScO+2 only for CnSc+ with odd n. In the case of C6Sc+, the loss of 2C neutrals, leading to C4Sc+ production, was also observed. The estimated rate constants of CnSc+ + O2 reactions were found to alternate in magnitude with the cluster size; CnSc+ clusters with even n have rate constants much lower than those with odd n.
